RAZOR-BLADE MULDER..

Specification of Letters Patent.

Patented duly n, 192th'.

.To all whom it may concern."

l-Se it hnown that l, Roninrr lt. BAILEY, a

citizen of the United States, residing at Chicago, in the county of @ook and State of illinois, have invented certain new and useful lmprovements in Razor-Blade' Holders, of which the following is a specification. rFhis invention relates to holders forsafety razor blades, particularly that type of blade having three holes down its center line. lt has for its object the provision of a holder by means of which a safety razor blade of this character may be held so as to expose a portion of its blade for the purpose of severing the threads of a seam, or the like. There are many other incidental uses for a device of this character possessing a very sharp and fairly small cutting edge.

.d further object is the provision of a folding holder for a blade of this character which will cover the edges of a blade when not in use so as to protect the user from injury in ease it is inadvertently grasped.

Still another object is the provision of a simple holder cheaply made in which old safety razor blades may be placed and used for various purposes after they have become unsuitable for use in a razor. By this means l provide a simpleand cheap knife having a much sharper bladethan that found in commercial knives.

l contemplate inclosing a razor blade having three holes along` itscenter line with a holder which will cover the blade when not in use and expose either edge, as desired, when in use.

The invention consists in the novel con structions and devices to be hereinafter described and claimed for carrying out the above stated objects and such other incidental. objects as will appear from the following description of a preferred embodiment of the invention shown in the drawing annexed hereto.

ln the drawing,

Figure 1 is a perspective view showing the device in 'what may be termed closed position.. i

Fig. Q is a perspective view of the device with the handles together and exposing a portion of the cutting edges of the blade.

Fig. 3 is a plan view of the device as shown in Fig. 1.

Fig. d is a section along the line IIll-mt of lili il.

Fig. 5 is a longitudinal section of the device as shown in Fig. 2.

Lilie characters of reference designate like parts in the several. figures of the drawing.

.ln the drawing ll. have shown a safety razor blade 1() of the type having two cutting edges on opposite sides thereof and having three holes 1 1, 12 and 13 down its center line. llt will be readily understood that the holder is applicable for two different types of blade by making slight changes requiring only slight skill and coming within the terms of my invention. rlhe blade is covered on opposite sides by portions 1d and 15 pivoted at 16 to the central hole 11. rllhese portions are provided with short handles 17 and 18 for grasping the device when in use. rllhe handles are made short, as shown especially in Fig. 2 so that it will be necessary to grasp the device close to the edge ofthe blade, thus clamping it tightly and preventing turning. However, l have shown means 19 for engaging the blade to prevent turning comprising struck up portions 20 which snap through the openings 12 and 13 and into recesses 21 formed in the other half 14C of the holder. By means of this arrangement it will be seen that the parts 1d and 15 may be rigidly held either in extended relation, as shown in Figs. 1 and 3, or in closed relation as shown in Fig. 2. lWhen the device is as shown in Figs. 1 and 3 it will be noted the blade is entirely covered and injury cannot result by inadvertently grasping it. l forni the parts 111, 15 sufficiently large so that a slight edge 22 extends beyond the cutting edges of the blade. lff desired, the parts lll, liinay be formed slightly concaved so to more completely cover the cutting edges of the blade.

lt is possible, as suggested above, to use a blade having only a central opening', the grasping of the handles sufiiciently clamping the blade to prevent turning. lt is desirable, however, for the purpose of convenience, to construct the device with the fastening devices as shown in the drawing.

l claim:

1. ln a device of the class described, the combination with a safety razor blade having a central opening, of a holder comprising two reversible portions covering a portion of the sharp edge of the blade and between which the blade is located, said portions being secured to the blade through the 'liti amk central opening, whereby when they are together they form a handle for the blade and whenone is turned in the opposite direction they shield the cuttingl edges of the blade.

2. In a device of the class described, the combination with alsa'fety; razor blade having a central opening, of a two-part holder, each part comprising a sheath portion of a size to cover more than half of the cutting edge of the blade, and a short handle portion extending therefrom, said parts being pivoted on opposite sides of said blade through the central `opening whereby when the handle portions are together a portion of the cutting edge of the blade is exposed and when they extend in opposite directions said edge is covered and protected.

3. In a device of the class described, the combination with a safety razor blade having a central opening, of a two-part holder, each part comprising a sheath portion of a size to cover more than half of the cutting edge of the blade, and a short handle portion extending therefrom, said parts being pivoted. on opposite sides of said blade through the central opening whereby when the handle portions are grasped together they clamp the blade to prevent it from turning. Y

4. In a device of thel class described, the combination with a safety razor blade having a central opening, of a holder formed in two parts pivoted to the blade through the central opening and between which parts the'blade is held, said parts having short handle vportions and means on said blade and holder for holding 'said parts either with their handles together or with their handles extending from-opposite sides of the blade.

5; A folding holder forl safety razor blades formed in two parts, each part having a portion for covering more than half of the cutting edges of a razor blade, and a short handle extending from one end thereof, and means for securing said portions to the center of a razor blade on opposite sides Vthereof sorthat when the handles extend in opposite directions the cutting edges of the blade arecovered and protected, and when they are together a portion of the edges are exposed.

f6. A folding holder for safety razor blades formed in two parts, each part hav- -ing a portion for covering more than half ofthe cutting edges of a razor blade, and a y short handle extending from one end thereof, and means for pivoting said portions to the center of the razor blade on opposite sides thereof, said parts being provided with means for holding the parts with their handles extended beyond the opposite ends of the blade and for holding them together at one end of the blade whereby a portion of the cutting edge is exposed.

7. A folding holder for safety razor blades having three holes along its center line, comprising two halves, each halt having a slightly coneaved portion for covering slightly more than halifi of the cutting edges of the blade, a removable pivot through said portions near one end thereof' for pivoting said halves through the central opening of the blade and on opposite sides thereof, one half having struck up portions to snap into the other openings in the blade and into recesses formed in the other hal fi, said halves having short handles thereon extending from the other end of said portions so that when they are grasped together a portion of the cutting edges of the blade will be exposed.

S. In an article of the class described, the combination with a safety razor blade having three openings along its central line, of: a two-part holder having portions thereof covering the cutting edges of said blade and between which the blade is located, said holder being pivoted to the blade through the central opening thereof and. having means engaging the other openings for holding the parts either in extended or closed relation.

9. A holder for safety razor blades formed in two parts, each part having a portion for covering more than halt of the cutting edges of the blade and having a short handle attached thereto, and means for pivoting the holder to a blade at its central portion whereby when the handles are together a portion of the blade is exposed and when they extend in opposite directions the blade is covered.

l0. In an article of the character described, the combination with a safety razor blade having two cutting edges, of' a twopart holder between which parts the blade is located and pivoted to the blade through its central portion, said holder having parts slightly concave and extending beyond and covering the entire blade when in extended relation, a portion of said parts being cut away so that when the holder is turned on the blade portions of the cutting edge thereof will be exposed.
